But the rock superstar was putting aside his grief to finalise arrangements for L’Wren’s funeral with her brother Randall Bambrough.

The pair have decided on a low-key ceremony in a secluded venue in LA. L’Wren’s body was this weekend being flown there from New York after officials confirmed her death as suicide.

Mick’s fellow Rolling Stones have decided not to attend for fear of attracting fans. And it is understood L’Wren’s sister Jan Sharpe will not be welcome because of a long-running family feud.

It comes as more details emerged of the steps Mick took to help keep L’Wren solvent. Official papers seen by the Sunday Mirror show her £3.4million New York apartment had been bought outright in 2010 and sources claim it was Mick who footed the bill.

Two years later he learned that former cover girl L’Wren, 49, had taken out a £760,000 re-­mortgage – and immediately paid off the debt.

A source said: “L’Wren was such a proud woman she never sought anything from Mick.

“She wanted to stand on her own two feet and make her own way in the world. It came from her Mormon upbringing.

“But when things started coming on top, Mick realised something was afoot. He shelled out millions trying to bail her out and the secret mortgage on the home was no different.

“He paid it off straight away. It is the kind of man he is.”

The property was placed in L’Wren’s company name, Scottland Management, when it was bought in 2010.

However on Valentine’s Day 2012, $1,250,000 (£757,000) was issued against the property. According to documents in New York, it was paid off in full on August 28 last year.

The ultra-posh building where L’Wren was found hanged is one of the most exclusive addresses in Manhattan - and one of the most expensive.

Some apartments in the striking Chelsea building can go for up to £12million.

The apartments come complete with James Bond-esque “sky garages” in which residents like Keith Urban, Nicole Kidman and designer Domenico Dolce can drive their cars in a personal elevator up to their apartments.

Apartment 9S, where L’Wren lived, is a 2,364-square-foot duplex with three bedrooms and three bathrooms.

Today a well-placed source also played down the extent of Jagger’s debts at the time of her death.

The source said:: “L’Wren owed around £2 million when she died, nothing like the figures that have been banded around.

“Mick Jagger was a lot more pro-active in helping ease L’Wren’s finances that had previously been reckoned.

“He was there for her all right, both as a partner, and as a financial support.”

The Rolling Stones will be back on tour in nine weeks after devastated front man Mick Jagger has had time grieve for his loss.

The 70-year-old - along with bandmates Keith Richards, Charlie Watts and Ronnie Wood - abandoned gigs in Australia and New Zealand after news of the fashion designer’s suicide broke on Monday.

But we can reveal they will return to the stage on May 26 in Oslo.

The four new dates – including the Rockin’ Rio Festival in Lisbon on May 29, Zurich on June 1 and Tel Aviv three days later – had been rumoured to be added to the tour schedule before L’Wren’s death, but have now been given the final nod.

L’Wren, 49, was found dead after hanging herself in her Manhattan apartment on Monday morning.
